Measures for acceptance standards and rapid analysis to transform residual soil into resources.

This is a soil survey solution focused on recycling that strongly promotes the transition from "waste" of construction-generated soil and excavation residual soil at construction sites to "resource utilization," achieving both a reduction in environmental impact and a dramatic compression of residual soil disposal costs. Under the reliable technology of a Ministry of the Environment-designated survey organization, we conduct high-precision soil analysis and effective sampling that strictly adhere to official methods, quickly providing official evidence that fully meets the stringent acceptance criteria set by the destination sites, public works, and recycling facilities. By appropriately controlling soil contamination risks through meticulous historical investigations, we scientifically prove that the generated soil is a clean resource containing no specific hazardous substances, completely eliminating secondary contamination issues at the relocation site. With GeoTech's abundant ground survey data and speedy analysis system, we significantly enhance cost minimization at the site and contribute to a circular economy at a high level. This service is the optimal choice for thoroughly reducing your business risks and maximizing cost performance, serving as a solid foundation to ensure reliable safety in many construction projects.
